175 US BBL Brewhouse and Siemens PCS7 Upgrade

Case study

175 US BBL Brewhouse and Siemens PCS7 Upgrade

Location: Spoetzl, Texas

Scope: Overall process design and build of complete 175 US beer barrel (BBL) Brewhouse

Briggs of Burton were involved in the design, engineering, and supply of specialist brewing equipment and automation to the new brewhouse for Spoetzl Brewery in Shiner, Texas. Owned by The Gambrinus Company, the Spoetzl Brewery is the oldest independent brewery in Texas, first producing beer in 1909.

The expansion project involved the integration of a second stream into the existing Briggs of Burton Brewhouse and upgrading the existing brewstream to include a new Brew Receiver and wort pre-heater. The project allows up to 175 US BBL x 12 Brews per Day (BPD) through the upgraded Brewhouse and milling system. As part of the engineering design, optimisations to water, energy and CIP were identified and realised through modifications including a Briggs Energy Recovery System. Briggs of Burton also provided the automation and control for the new equipment based on Siemens PCS7.
